Maybe not problems but real injuries. A friend of mine just injured his back leg going numb ended up in emergency surgery. Just like that, no particular event. they said "you're fine" then next day, no leg. This is the second one in 1 year I personally know of that this happened to. I have also met quite a few who had surgery, healed up and continued on with their life. One told me "oh, back problems, I had that, surgery, no big deal. Just get minimal surgery and you'll be fine" (not quite). My problems started for real in my 20s and went really downhill from there. Now in my 40s my spine seems to be a wreck and needs to be held together by metal.
